Detailed Description

Describes a pixel coordinate on the global grid of pixels. Range is determined by magnification, e.g. for a tile size of 256 and a magnification of 2 the global grid is 1024x1024 pixels. For a magnification of 10, the global grid is 262144x262144 pixels.

Member Function Documentation

int MAP::PixelCoordinate::getX (   )  const [inline]

Returns the horizontal (longitude) component of the pixel coordinate.

int MAP::PixelCoordinate::getY (   )  const [inline]

Returns the vertical (latitude) component of the pixel coordinate.

int MAP::PixelCoordinate::getMagnification (   )  const [inline]

Returns the magnification component of the pixel coordinate.

bool MAP::PixelCoordinate::operator== (  const PixelCoordinate &  b  )  const [inline]

Compares two pixel coordinates, returns true if the first coordinate is equal to the second.

bool MAP::PixelCoordinate::operator!= (  const PixelCoordinate &  b  )  const [inline]

Compare two pixel coordinates, returns true if the first coordinate is not equal to the second.
